Here is one of the unusual crank sensors that might be useful if wanting a trigger wheel for an after market ECU, or removal of the internal trigger wheel that may fail at sustained high revs. It is for a small block but believe some of the larger engines got this at some point too. http://cgi.ebay.co.uk/volkswagen-au...arts_Vehicles_CarParts_SM&hash=item2eb0d7e485 Not sure how to save the pic from the ad so it is still viewable once the ad drops off ebay.
I thought they'd upped the security for a moment, but I'd just forgotten it. For Firefox enlarge the eBay picture, Right-click the picture to get the pop-up menu, then left-click on "View Page Info" Left-click on the "Media" icon at the top of the "Page Info" pop-up page. The image should be auto selected for the "Save As" button and previewed at the bottom. EDIT: Cheers, as I remember google and a bit trial and error.
this is small block only fitment afaik, part numbers for you: 030 103 171 K - polo crank sensor flange, M6? - 58.83+VAT 030 103 171 H - polo crank sensor flange, M5? - 58.83+VAT 030 957 147 G - polo crank sensor, M6? - 63.24+VAT 030 957 147 B - polo crank sensor, M5? - 63.24+VAT iirc its direct fitment except 1 bolt hole doesnt line up. someone had a post about them and they did a bit of grinding on the block so the sensor could be swapped without taking the gearbox off
The mk4 X-flow engines have a similar arrangement, which probably fits the older "big blocks", better.
What engine size? My AKL alloy block 1.6 8v has the internal trigger wheel. Is it the 2.0 engines that have this?
I think there were some big block engines that got a similar setup though. I was looking for a long nose crank out of an 06X type block. I came across an AGM? crank and rods that looked like it did not have the internal trigger wheel fitted on the crank. The pic was not great but the trigger wheel cranks look a little different at the no4 crankpin where the trigger wheel fits. Is it possible to search on the AGM engine code on ekta? I think that was the code and it was a 20v iirc.
yeah click the menu button in etka, then identification codes -> engine code gives complete list of all engine codes, AGM doesnt exist though, did you mean AGN?
It could have been, or the item was listed wrong I suppose. It certainly looked like a long nose (chain driven oilpump) crank with no internal trigger wheel. The very thing I was looking for. It would be great to know if there were cranks that did not run this internal wheel as std though. It would be a good starting point for high revving applications.
APK & AQY 2.0 X-flows are internal. Haynes refers to the sensor as a crank speed sensor, (AEH & AKL 1.6 too) so there may not be a reference tooth for crank position...
there are a number of threads on this both on hear and Vortex and in Brookster's thread vortex http://www.clubgti.com/forum/showthread.php?t=200075 edit and this one http://www.clubgti.com/forum/showpost.php?p=1791780&postcount=15
ok that means the AGN has the missing tooth too, both AGN and AKL share the same crank sensor part number
This is a different advert but it does not have an trigger wheel attached. Not sure if the seller has unbolted it. kind of unnecessary to do that really. AHG is the code. http://cgi.ebay.co.uk/VW-AUDI-CRANK...arts_Vehicles_CarParts_SM&hash=item45f5fb5d67
AHG is 99 Polo 1.9 TDI (long throw conversion for 06x block perhaps?) part number is 028 105 101 R. both of these engines have a 'speed sensor ring' which doesn't look the same as the impulse sensor ring. it looks kinda flat and 'fitted' over the end of the crank if that makes any sense? it shares the crank with the AKU, AHB and AKW code engines Engines fitted to: 96-03 Caddy 99-06 Lupo 95-02 Polo/Derby/Classic/Variant 97-04 Arosa 96-03 Inca piccy of what I mean, need to be signed up for VAGCAT to see it I expect (part 6):
Hmm, that just looks like the internal trigger wheel to me. The TDI ones have just the 1 or 4 cutouts it would seem unlike the petrol that have the missing tooth. That AHG crank will be a 95.5mm stroker crank for a 06X block 20v though.
